Compressor
Replacement
lf the compressor is marginally operable. run the
engine at idie speed, and let the air conditioner
work for a few minutes. then shut the engine off.
Disconnect the negative cable from the battery.
Recover the refrigerant with a recovery/recycling/
charging station (see page 22-59).
Disconnect the condenser fan connector. Remove
the compressor clutch connector and the wire har-
ness clip from the condenser fan shroud, then dis-
connect the compressor clutch connector. Remove

Clutch Inspection
Check the plated parts of the armature plate for color
changes, peeling or other damage. lf there is dam-
age, replace the clutch set.
Check the rotor pulley bearing play and drag by rotat-
ing the rotor pulley by hand. Replace the clutch set
with a new one if it is noisy or has excessive play/drag.
Measure the clearance between the rotor pulley and
the armature plate all the way around. lf the clear-
ance is not within specified limits, the armature plate
must be removed and shims added or removed as
required, following the procedure on page 22-66.
Cloarance: 0.5 t 0.15 mm {0.020 t 0.q)6 in)
NOTE: The shims are available in four thicknesses:
0.1 mm. 0.2 mm. 0.4 mm and 0.5 mm

. Release the field coil connector from the holder, then
disconnect it. Check the thermal protector for conti-
nuity, lf there is no continuity, replace the thermal
prorecror.
NOTE: The thermal protector will have no continuity
above 251.6 to 262.4"F 1122 to 128"C). When the tem-perature drops below 240.8 to 219.8"F (116 to 104'C),
the thermal protector will have continuity.
Check resistance of the field coil.
Field Coil Resistance: 3.2 i 0.15 ohms at 68"F {20'C)
lf resistance is not within specifications, replace the
field coil.

Reassemble the comDressor clutch in the reverse
order of disassembly. Make note of the following
rrems.
Install the field coil with the wire side facing down,
and align the boss on the tield coil with the hole in
the compressor.
Clean the rotor pulley and compressor sliding
surfaces with non-oetroleum solvent.
lnstall new snap rings A and B.
Make sure the snap rings are fully seated in the
groove.
Make sure that the rotor pulley turns smoothly
after it's reassembled.
Route and clamp the wires properly or they can
be damaged by the rotor pulley.

Troubleshooting
Tips and Precautions
Bef ore Troubleshootin g
. Check applicable fuses in the appropriate fuse/relay
box.
. Check the battery for damage, state of charge, and
clean. and tight connections.
. Check the alternator belt tension.
CAUTION:
. Do not quick-charge a battery unless the battery
ground cable has been disconnected, otherwise you
will damage the alternator diodes.
. Do not attempt to crank thc engins wilh the battery
ground cable loosely connected or you will severely
damage the wiring.
Handling Connestors
. Make sure the connectors are clean and have no loose
wire terminals,
. N4ake sure multiple cavity connectors are packed with
grease (except water-tight connectors).
. All connectors have push-down release type locks.
Some connectors have a clip on their side used to
attach them to a mount bracket on the body or on
another component. This clip has a pull type lock.
Some mounted connectors cannot be disconnected
unless you first release the lock and remove the con-
nector from its mount bracket.
LOCKINGPAWL ONOTHERHALF OFPulltodisengage
LOCKING TAB
CONNECTORBRACKET
Never try to disconnect connectors by pulling on
their wires; pull on the connector halves instead.
Alwavs reinstall olastic covers.
Before connecting connectors, make sure the termi-
nals are in place and not bent.
. Check for loose retainers and rubber seals.
RETAINER
The backs of some connectors are oacked with
grease. Add grease if necessary. lf the grease is con
taminated. reolace it.

Handling Wires and Harnesges
. Secure wires and wire harnesses to the frame with
their respective wire ties at the designated locations.
. Remove clips carefully; don't damage their locks.
Slip pliers under the clip base and through the hole at
an angle, then squeeze the expansion tabs to release the
clrD.
After installing harness clips, make sure the harness
doesn't interfere with any moving pans.
Keep wire harnesses away from exhaust pipes and
other hot parts, trom sharp edges of brackets and
holes. and from exoos€d screws and bolts.

T€sting and Repairs
. Do not use wires or harnesses with broken insulation.
Replace them or repair them by wrapping the break
with electricaltape.
. After installing parts, make sure that no wires are
pinched under them.
. When using electrical test equipment, follow the
manufacturer's instructions and those described in
this manual.
. lf possible, insert the probe of the tester from the
wire side (except waterproof connector).
. Seat grommets in their grooves properly.
. Use a probe with a tapered tip.
Refer to the instructions in the Honda Terminal Kit for
identification and replacement of connector termi-
nals.
